How to Use Timestamp Converter

The Timestamp Converter works in both directions. To convert a timestamp to a date, paste the Unix timestamp — the tool auto-detects seconds vs milliseconds and shows the corresponding date in both UTC and your local timezone. To get a timestamp from a date, use the date picker or type a date string. The result shows both seconds and milliseconds timestamps. The tool also displays relative time ('2 hours ago', 'in 3 days') for quick context. Common timestamps like current time, start of day, and start of year are available as quick-access buttons.
